HDPE High Speed Screw Barrel

High-speed extrusion screw barrel optimized for HDPE materials. High throughput with energy-saving design for pipes, sheets, and injection molding applications.

Product Overview

Vanwell HDPE high-speed screw barrels are engineered for high-throughput polyethylene extrusion and injection molding processes. The optimized screw design features a specialized barrier flight geometry that delivers superior melt homogenization while maintaining high output rates.


Designed for energy efficiency and high productivity, our HDPE screws reduce cycle times and motor load while maintaining excellent melt quality. The bimetallic barrel lining provides exceptional wear resistance against the high-abrasion HDPE materials including carbon black filled and mineral-filled compounds.
